UGC Script Builder — Hooks, B-Roll & Ad Testing

Three seconds decide whether your ad works. Not the script, not the edit, not the offer — the opening. Most viewers scroll before your first sentence finishes, which makes the hook the single variable worth engineering properly. Almost nobody does.

This builder does. It is a Google Sheets template — open it, click Make a copy, and it is yours forever. No subscription, no writing skill required.

How it works

1. Open your copy of the builder
2. Fill Column D using the dropdown menus — 32 fields across 6 sections
3. Type your product details and your opening hook line
4. Five complete outputs appear instantly on the right
5. Film it, or paste into your AI video tool

The 5 outputs you get every time

• Full UGC Script — hook, problem, agitation, solution, proof, objection handling and CTA, structured and ready to film
• Five Hook Variants — five genuinely different angles on the same product, built for split testing
• B-Roll Shot List — six numbered shots, each matched to a specific beat in the script
• Voiceover and Delivery Brief — persona, pace, tone and how to sound like a person rather than an advert
• Caption and Test Plan — caption structure, hashtag mix, which metric to judge on and when to kill a loser

Hook engineering gets its own section

Six fields dedicated to the opening: hook type, your line, first frame visual, hook duration, pattern interrupt and hook emotion. Fifteen hook types — problem callout, curiosity gap, bold claim, negative hook, confession, us versus them, POV framing and more.

Plus the rules that actually matter: under ten words, show the problem rather than announcing it, put a pattern interrupt in the first second, and never open with an introduction.

Five hooks, one script

The cheapest test in paid social is a new opening line. This generates five — problem, curiosity, bold claim, negative and demonstration — each a different psychological angle rather than five rewordings of the same idea. Test them against one script, keep the winner, scale it.

Built for people actually running ads

• Judge on the three second rate, not total views — the builder says which metric to watch
• Change one variable at a time — three changes teach you nothing
• Kill losers fast and put the budget behind the winner
• Expect winners to fatigue — keep a queue ready
• A tired ad usually needs a new hook, not a new script

Compliance, because it costs accounts

Paid partnership disclosure. No health claims. No income claims. Results-not-typical qualifiers on any before and after. Platform ad policies differ and each bans different things. There is a dedicated field and a full library section, because getting this wrong is expensive in a way that a weak hook is not.
